摘要/Abstract

摘要： 探讨实时剪切波弹性成像（SWE）参数弹性模量值在乳腺癌腋窝淋巴结转移诊断中的价值。选取乳腺癌患者240例，给予SWE检查，均接受手术切除和腋窝淋巴结（ALN）切除术。ALN阳性组SWE图像呈硬化征、黑洞征、病灶弹性分布不均匀、病灶内部不均匀异常彩色、彩色硬度色谱呈红色的比例明显高于ALN阴性组（P<0.05）；ALN阳性组病灶弹性模量值最大值（E_max）、弹性模量值平均值（E_mean）、标准差（SD）和弹性模量平均值比值（E_ratio）明显高于ALN阴性组病灶（P<0.05）；Logistic回归分析显示病灶内部不均匀异常彩色、E_max、E_mean和E_ratio是乳腺癌患者发生ALN转移的影响因素（P<0.05）。SWE参数弹性模量值在乳腺癌发生ALN转移中有一定诊断价值，值得临床使用。

Abstract: The purpose of this study was to explore the value of real-time shear wave elastography (SWE) parameter modulus of elasticity in the diagnosis of axillary lymph node metastasis of breast cancer. A total of 240 breast cancer patients were selected for SWE examination, all patients underwent surgical resection and axillary lymph node (ALN) resection. The SWE images of the ALN positive group showed sclerosing sign, black hole sign, uneven distribution of the lesion elasticity, non-uniform abnormal color inside the lesion, and red of color hardness spectrum were significantly higher than those of the ALN negative group (P<0.05). The maximum value of elastic modulus (E_max), mean value of elastic modulus (E_mean), standard deviation (SD) and ratio of the average elastic modulus (E_ratio) in the ALN positive group were significantly higher than those in the ALN negative group (P<0.05). The results of Logistic regression analysis showed that non-uniform abnormal color inside the lesion, E_max, E_mean and E_ratio were the influencing factors for ALN metastasis in breast cancer patients (P<0.05). The value of the elastic modulus of SWE parameter has a certain diagnostic value in ALN metastasis of breast cancer, which is worth clinical use.
